On Oct. 3, word broke that she was supposedly going to perform at the Super Bowl XLVI Halftime Show in February. (Madonna's publicist, Liz Rosenberg, said "there is nothing to confirm or deny at this time.") Now, fan sites having been chattering about an alleged world tour, due to begin in March.

Madonna fan site DrownedMadonna.com received an email from an "unconfirmed insider" with a photo of a dodgy-looking press release on what appeared to be Live Nation letterhead. The statement listed alleged tour dates for a tour that would take Madonna on a tour of at least four continents, beginning in Auckland, New Zealand.

Contacted by Billboard, Rosenberg said the tour dates and press release are "fake."

Now, let's get back to guessing about what Madonna may perform at the Super Bowl. At least that rumor hasn't been shot down entirely yet.
